Idaho’s tallest residential tower rises 26 stories. Situated on a compact site at 12th and Idaho that was once occupied by a parking lot, the concrete core tower is clad almost entirely in glass with panoramic views of the city. It includes 18 residential levels, ground-floor retail, seven levels of parking and a two-level rooftop amenity deck.
As one of Boise’s first luxury high-rise residential towers, the Arthur responds to the city’s urgent need for higher density and expanded housing options while helping to revitalize the downtown area.
To meet the project’s aggressive two-year schedule, the team agreed to release key project packages ahead of design development and construction documents. Exterior wall systems, elevators, MEP and concrete were procured directly from schematic design documents.
Although a post-tensioned concrete structure is commonplace in other markets, such a tower had never been executed at this height in Boise, and a five-day deck placement cycle was critical to maintain the schedule. A Talon Wall system, which is a hybrid of curtain wall and window wall, was another first for the city. The contractor brought in a trusted installer from Chicago that hired local ironworkers and glaziers. Together, the team completed 100 units per floor in four days. Executing the structure and enclosure on schedule enabled a steady five-day interior trade cycle as well. This teamwide coordination effort enabled what was originally planned as a 30-month project to wrap up in just 26 months.
